Abstract

Systems, methods, apparatuses, and computer program products for conditional handover (CHO) execution with network slice service continuity prioritization are provided. A radio resource control (RRC) reconfiguration message sent by a source radio access network (RAN) node to the user equipment (UE) may include, for each CHO configuration, an associated network slice-related priority index. The UE may take this index into account when selecting a suitable cell during CHO recovery. Additionally, or alternatively, the RRC reconfiguration message sent by a source RAN node may include, for each CHO configuration, an associated network slice support information of the candidate target cell. The message may also include network slice remapping information for any network slice associated with one of the candidate target cells. Using the above network slice-related information received from the network, the UE can prioritize the cell to select during CHO recovery in case more than one suitable cell is available.
